Airbus always insisted that the A380 would climb to F350 at max weight and cruise at M0.85 - yes, it can do that, but not in an operational sense so it's desirable to know what the true capabilities of the A350 are.
Going Boeing, LRC in the A350 is M0.85, so it is every bit as capable as the 787, perhaps even more so. Looking forward to getting my hands on it from next Feb.
